What are peptides? Manufacturing (SPPS), purity (HPLC), lyophilization. With 7 PubMed references. A scientifically grounded guide.
Our guides provide comprehensive, scientifically grounded information on research peptides. Every article is editorially reviewed by Dr. Sieglinde Klaus and includes references to peer-reviewed studies from PubMed. From detailed monographs on individual peptides to practical protocols and comparative analyses, researchers will find all relevant data on mechanisms of action, dosages, storage, and current study results.
All peptides featured in our guides are available from BergdorfBio in research grade, with HPLC purity of at least 99% and batch-specific certificates of analysis (CoA). Guides are updated regularly as new research findings are published.
